| Abstract: | A review with 45 references is given on technology and application of trace analysis for pre-enrichment technology. This paper outlines the recent development at home and abroad and describs the main methods and their features. A lot of facts have show that the preconcentration has been used for trace analysis with satisfactory result and low detection limit. |
